I've had my dog since she was about 6 weeks old & she is now 3 years old . She's a very good girl . Never really cries , sleeps , plays . She has never given me any trouble . I got a new puppy back in july & he is now 6 months old . My female & male both stay in mine & my sisters room . The first month we had them in the same room neither one of them barked at each other or cried for eachother . Just a few days ago , my female dog started whinning . She whines if we leave , she whinnes when we're here . Could someone tell me why this is going on ? I knw she is not injured and she's not being neglected . Any advice or explination ? Please . Anything will help . No rude or mean comments please .
